I experience issue after update too.
The database afterUpdate hook is not working on the Live Site(works well in editor)
On another site the chart in the HTML element do not load. Maybe the issue is with the messaging between Wix Code and HTML element. (also works well in editor, but not LIVE)
Please, let me know if you know about those issue and when it will work again. Thanks.
Anyway, the speed update is awesome, but hope to get other things get fixed soon.
